Instruments, systems and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, and a mucosal resection device. Systems include a combination of one or more of such instruments with or without injectable agents. Embodiments of various methods for performing the procedures are also provided. In accordance with one aspect there is provided a submucosal implant device for diagnosing and treating disorders of the body. The submucosal implant device may take the form of a gastric stimulator in which signals are supplied to the muscular wall of a mammal to treat motility disorders. In accordance with yet another aspect there is provided a method for performing a submucosal medical procedure to deploy a submucosal implant device in the digestive tract of a mammal.

Devices, systems and methods are provided for performing intra-lumenal medical procedures in a desired area of the body. Stents, stent delivery devices and methods of performing medical procedures to redirect and or re-establish the intravascular flow of blood are provided for the treatment of hemorrhagic and ischemic disease states.
摘要:
A vascular occlusion device deployment system for placing an occlusion device at a preselected site within the vasculature of a patient. The deployment system employing a pusher having a lumen with an opening at the distal end of the pusher. A vascular occlusion device is connected to the distal end of the pusher by a portion that is removeably disposed within the opening. The portion of the occlusion device is forced out of the opening by an expandable reaction chamber, thereby deploying the occlusion device. The expandable reaction chamber, prior to deployment, has multiple chambers separated by a heat-dissolvable membrane. When the membrane is dissolved, components from the chambers react and expand, leading to deployment.

Devices, systems and methods are provided for performing intra-lumenal medical procedures in a desired area of the body. Retrieval devices and methods of performing medical procedures to remove foreign objects to re-establish the intravascular flow of blood are provided.
摘要:
An endoscopic tissue grasper device includes a flexible tubular member, a flexible shaft extending through the tubular member, a proximal handle for moving the shaft and tubular member relative to each other, and a distal helical coil having a sharpened end for engaging tissue. The helical coil has a proximal close wound portion, a distal open wound portion, and an intermediate transition portion between the proximal and distal portions. The flexible shaft extends into the proximal and intermediate portions and is secured thereto, which prevents tissue engaged by the helical coil from becoming wedged in the transition portion and thereby facilitates release of the coil from engaged tissue. In addition, a bearing sheath is provided between the shaft and tubular member to prevent the shaft from binding during operation.

摘要:
The present invention relates to a medical device for placement at a predetermined location within a passageway of the human body, and more particularly, relates to a flexible embolization device which may be delivered by a catheter to a pre-selected position within a blood vessel to thereby embolize a blood vessel or a blood vessel defect, such as an aneurysm or fistula. Specifically, the embolization device comprises an elongated coil having a lumen, the coil and lumen being at least partially embedded in an elongated foam member comprising, in some embodiments, a flexible, biodegradable, water insoluble, open, interconnecting-cell foam material having embolic characteristics, and capable of allowing cell proliferation into the open cell foam interior.
摘要:
An endoscopic suturing system and method are disclosed as are devices for use with the system and method such as a suture dispenser, a cinch device, and a tissue grasper. In one embodiment the suturing system includes a cap assembly arranged at the distal end portion of an endoscope or guide member, with the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope or guide member. A needle capture device may be inserted through a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue.
